Hi! New to groupand wonder if anyone can steer me to find a buttstock adapter to use a 1928a-1 sliding buttstock on my 1927a-1? Kahr and Numerich do not have. Can a 1928a-1 lower frame assembly fit the 1927a-1-I do not want FA capabilities. Just want to get a FBI case that holds gun and mags but buttstock must be removed. Thanks-Joe
